12x - 5 = 8x - x + 50 Help please show work and check the solution

Inga [223]

Answer:

x = 11

Step-by-step explanation:

$12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11$

and check:

$12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127$

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2

drek231 [11]

Respuesta:

175 rad / s²

Explicación paso a paso:

Dado que :

Velocidad angular final = 350 rad / s

Tiempo empleado = 2 segundos

La aceleración angular, a =?

Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo

(velocidad final - Velocidad inicial) / tiempo empleado

Velocidad inicial = 0 rad / s

Aceleración angular = (350 - 0) / 2 = 350/2

= 175 rad / s²

A dolphin jumps out of the water with

Mandarinka [93]

Answer:

$t=1.25\ sec$

Step-by-step explanation:

we have

$h(t)=-16t^{2}+20t$

where

t is the time in seconds

h is the dolphin's height in feet

we know that

When the dolphin return to the water the value of h(t) is equal to zero

For h(t)=0

$0=-16t^{2}+20t$

$16t^{2}=20t$

Simplify

$16t=20$

$t=\frac{20}{16}$

$t=\frac{5}{4}=1.25\ sec$

see the attached figure to better understand the problem
